Summary: MIME handling very dumb, breaks messages
Initial Comment:
Mailman delivered a partially garbled message on a
mailing list today because it doesn't handle
non-text/plain messages. The incoming message was:
Content-Transfer-Encoding: base64
Content-Type: text/plain;charset="utf-8"
So the content was something like this:
QW55b25lIG91dCB0aGVyZSB1c2luZyBNUlRHIHRvIGNvbGxlY3Qgcm91dGVyIGRhdGEgLCBJZiBz
byB3aGF0IGtpbmQgb2YgYmFja2VuZA0KYXJlIHlvdSB1c2luZyBJIGFtIHRyeWluZyB0byBjb25m

d2F5IHRvIGdvIGFib3V0IHRoaXMNCiANCiANCiANCg==
To which Mailman blindly attached a text/plain
signature (rather than another mime section and marking
the body as mixed), which then decodes in any MIME
aware mailreader as a large blob of lower-ASCII crap:
I&#65533;$j&#65533;(&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;&#65533;Lj)b&#65533;&#65533;&#65533;"&#65533;;
&#65533;&#65533;&#65533;Z&#65533;&#65533;&#1886;&#65533;&#65533;&#65533;&#65533;{&#65533;&#65533;&#65533;&#65533;z(&#65533;X&#65533;&#65533;&#1511;Z&#65533;&#65533;r&#65533;}:-&#65533;&#65533;ej^&#65533;&#65533;+
&#65533;&#65533;&#65533;+&#65533;&#65533;b&#65533;v&#65533;&#65533;&#65533;m&#65533;&#65533;b&#65533;&#1447;v&#731;&#65533;&#65533;&#65533;&#1576;&#65533;f&#65533;j&#65533;z{`&#65533;&#65533;zm&#65533;&#65533;&#65533;a&#65533;&#65533;&#65533;o&#65533;j)
fj&#65533;&#65533;b&#65533;&#65533;?slg=
Please adjust the behaviour to not append a signature
if it can't attach it in such a way that data is not
garbled.
